In this study, the electron coefficients; Mean energy , Mobility and Drift velocity of different gases Ar, He, N2 and O2 in the ionosphere have been calculated using BOLSIG+ program to check the solution results of Boltzmann equation results, and effect of reduced electric field (E/N) on electronic coefficients. The electric field has been specified in the limited range 1-100 Td. The gases were in the ionosphere layer at an altitude frame 50-2000 km. Furthermore, the mean energy and drift velocity steadily increased with increases in the electric field, while mobility was reduced. It turns out that there is a significant and obvious decrease in mobility as a result of inelastic collisions and in addition little energy gained by the reduced electric field. A clear mathematical model was obtained to find out the electronic coefficient values without a simulation program (BOLSIG +). In addition, this model shows a strong correlation between the current work and the electronic transaction values calculated through the BOLSIG+ program.
Western political philosophy is one of the philosophies that dealt with many ideas and proposals that include concepts born in ancient times, where Greek philosophy represents the basic roots of the development of political thought and the study of political phenomena and a starting point for political thought, and if the matter is completed with the Romans, and schools of thought that represented a model for building the state And up to the modern era, the absolute and the relative were the subject of discussion by most philosophers, the transition of thought was with Descartes, and the intellectual transformation from the absolute to the relative was with Nietzsche, and the basic root of all of that is represented by the German philoso

Appearance of the Kurdish press in the Kurdish literature was affected by as set of both external and internal factors. The former was realized in the spreading of press and publications especially at the neighboring countries in the second half of the 19th century. The latter factors, external ones ,were concerned the political situations undergone by the Kurdish people who severely suffered injustice practiced by the Othman authority .All these reasons had driven the educated to migrate to search for more safe places to practice their cultural actions with absolute freedom. Consequently, the first newspaper was issued on 22/4/1898 in Cairo which pointed the birth of the Kurdish press inside and outside Kurdistan region which
